HENRY c. FISK, or STAFFORD, CONNECTICUT.
STABILIZER FOR AEROPLANES.
Specification of- Letters Patent.
Patented Dec. 30, 1913.
Application filed April 2, 1913. Serial No; 758,408.
To all whom it may concern:
Be it known that I, HENRY C. FISK, a citizen of the United States, residing at Stafford, in the county of Tolland and State of Connecticut, have invented certain new and useful Improvements in Stabilizers for Aeroplanes, of which the following o is a specification.
My invention relates to certain new and useful improvements in stabilizers for aeroplanes, and the object of my invention is to provide a device of this character which is adapted to be attached to an aeroplane of any type which may be found desirable, whether the same is a monoplane, a biplane, or of other construction, and which attachment will operate to keep the machine to which it is attached in its proper upright position and prevent overturning.
A further object of my invention is to improve the construction shown in my application Serial Number 745,984, filed February 3, 1913, by providing means whereby the stabilizer shown in said application may be adjusted for various atmospheric conditions. 4
With the foregoing and other objects in view my invention comprises broadly the placing of a plane, preferably of circular, or similar outline, above the supporting plane or planes of the machine, and in providing means whereby the edge portion of said plane can be adjusted at various angles to the body portion thereof.
My invention further consists in certain constructions, combinations and arrangements of parts, the preferred form of which will be first described in connection with the accompanying drawing and then the invention particularly pointed out in the appended claims.
' Referring to the drawings wherein the same part is designated by the same reference numeral wherever it occurs, Figure 1 is a front elevation of an outline of a biplane with my invention attached thereto, the same being shown partly in section. Fig. 2 is a top plan view of the construction shown in Fig. 1 and Fig. 3 is a detail perspective view of an adjusting means for the stabilizing plane.
5 designates an aeroplane shown as being of biplane type. It is to be understood however that the particular type of aeroplane forms no part of my invention.
Extending upwardly from the top of the supporting plane of the biplane are uprights G of any suitable height, and 7 are the guys by means of which the uprights 6 are rigidly held against the strains to which they maybe subjected. Secured to the upper ends of the uprights 6 is my improved stabilizing plane 8. This plane can be constructed out of any suitable materials and in any suitable way, provided however that it is so constructed that its edge portion may be flexed with relation to the main portion thereof. It is also entirely immaterial to my invention what particular means are employed to support the plane. As illustrating one means by which the edges of this stabilizing plane may be flexed I have shown a central hollow post 9 extending from the upper supporting plane of the biplane, through the center of the stabilizing plane 8 and wires 10 connected at one end to the periphery of the stabilizing plane and passing over the outwardly curved portion 11 formed at the upper end of the hollow post 9, and then down through the post to a shaft 12, mounted on a cross brace 13 on the main frame of the aeroplane, said shaft 12 being provided with a hand wheel 18 whereby the same may be rotated. I have shown the wires 9 as being connected to a single wire 14 wound upon the shaft 12 to avoid a multiplicity of wires being twisted around the shaft 12.
15 designates a series of wires connected at one end to the periphery of the stabilizing plane 8, and at the other end connected to a second shaft 16, through a single wire.
hand wheel 18. It is to be understood how ever that any other form of mechanism desired may be employed to flex the edge of my stabilizing plane without departing from my invention, and also that the size of the flexible portion can be varied as desired.
I have illustrated my stabilizing plane as being composed of two overlapping parts, each part having a semi-circular rod 19 in its periphery, these rods at their ends overlapping and passing through eyes 20. From this construction it will be seen that by turning the hand wheels 13 and 18 in the proper directions the curvature of the edge of thestabilizing plane can be changed. That is to say the plane can be flexed so that its edge will extend upward, or downward, or, if desired, the entire plane can be made flat.
I am aware that considerable variation is possible in the details of construction herein shown and described, Without departing from the spirit of my invention, and I do not'intend to limit myself thereto, except as pointed out in the following claims, in which it is-my intention to claim all the novelty inherent in the structure shown and described as broadly as the state of the art will permit.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is: I
1. The combination with a supporting plane of an aeroplane, of a stabilizing plane,
means for supporting the stabilizing plane above the supporting plane, said stabilizing plane having a central fixed plane portion surrounded by a flexing portion, and means for flexing the outer portion.
2. The combination with a supporting plane of an aeroplane, of a stabilizing plane,
means for supporting the stabilizing plane above the supporting plane, said stabilizing plane having a central fixed plane portion surrounded by a flexing portion, an operating mechanism, and Wires connecting the 1 periphery of the stabilizing plane to the operating mechanism whereby the angle be tween the peripheral portion of the stabilizing plane and the central fixed plane portion thereof may be varied.
3. The combination with the supporting plane of an aeroplane, of a stabilizing plane, means for supporting the stabilizing plane above the supporting plane, said stabilizing plane being of circular form and comprising a central fixed plane portion surrounded by a flexible portion, and means whereby the angle between the flexible portion and the central portion can be adjusted.
In testimony whereof I aflix my signature in presence of two witnesses.
